[llvm-dev] llvm-objdump print file offset

[Jordan Rupprecht via llvm-dev]

I have an ancient patch where I fixed this, see
https://reviews.llvm.org/D68669. But it was more of a proof of concept,
with lots of TODOs & no tests written for it (just existing tests updated).
If someone wanted to take that patch and iterate on it, that might be
faster than waiting for me.
